BTQ Technologies Corp. (BTQ) Stock: Plunge 7% as Bitcoin Quantum Testnet Rolls Out BIP 360 Upgrade

TLDR

• BTQ rolls out BIP 360 for quantum-safe Bitcoin testing on a new testnet.
• Pay-to-Merkle-Root (P2MR) hides public keys to protect against quantum attacks.
• Testnet includes full wallets for creating, funding, and broadcasting P2MR txs.
• Quantum-resistant upgrade works now, but adoption faces social and governance hurdles.
• Bitcoin Quantum is a separate chain; old addresses remain exposed to quantum risk.

BTQ Technologies Corp. (BTQ) shares fell sharply to $2.5450, down 7.12%, during late morning trading. The decline followed the company’s announcement of a major upgrade to its Bitcoin Quantum testnet. The release introduces a working implementation of a quantum-resistant transaction model tied to Bitcoin.

Bitcoin Quantum testnet activates BIP 360 functionality

BTQ confirmed that Bitcoin Quantum testnet v0.3.0 now runs the first working version of Bitcoin Improvement Proposal 360. The upgrade introduces Pay-to-Merkle-Root outputs designed to improve resistance against future quantum threats. The company moved the proposal from concept into a functioning test environment.

The implementation enables full transaction processing using quantum-resistant structures within the test network. It supports address creation, validation, and transaction execution using updated cryptographic methods. As a result, developers can test these features in a live blockchain setting.

The release also integrates post-quantum signature verification using Dilithium-based operations. These features operate within the tapscript framework and support secure transaction validation. Consequently, the system demonstrates a practical path toward quantum-safe blockchain infrastructure.

Upgrade targets long-term Bitcoin security risks

BIP 360 addresses concerns tied to public key exposure under existing Bitcoin structures. Current designs may face risks if quantum computing advances weaken cryptographic protections. Therefore, the proposal removes key-path spending to reduce this exposure.

The new output model commits directly to a Merkle root instead of relying on traditional key mechanisms. This structure maintains scripting flexibility while removing vulnerable components. As a result, it preserves functionality without increasing long-term risk.

Bitcoin’s upgrade process remains slow due to its conservative governance model. Previous updates required several years before full adoption across the network. Therefore, BTQ’s testnet aims to accelerate experimentation without waiting for consensus.

Testnet expansion and policy pressure shape rollout

Bitcoin Quantum testnet v0.3.0 also introduces faster block intervals and updated emission parameters. The network now targets one-minute block times to support rapid testing cycles. It maintains Bitcoin-like supply mechanics through structured halving schedules.

The platform has recorded over 100,000 mined blocks and participation from more than 50 miners. It also supports a growing contributor base focused on post-quantum development. These metrics indicate steady progress across multiple testnet iterations.

Regulatory timelines continue to push adoption of quantum-resistant cryptography. Governments in the United States, Europe, and Canada have set deadlines for transition planning. BTQ positions its infrastructure to align with emerging compliance and security requirements.
